Cooper Bussmann NON-3/4 Cartridge Fast-acting Fuse 0.75A

Product Description

The COOPER BUSSMANN NON-3/4 is a K5-class, fast-acting cartridge fuse rated at 0.75 amps. It is designed for general-purpose overcurrent protection in low-amperage circuits across a wide range of industrial and commercial control applications. The cartridge body measures 2 inches in overall length and 0.563 inches in diameter, fitting standard fuse holders used by electricians and equipment technicians. Its fast-acting response characteristic means it opens quickly on overload, protecting sensitive downstream components without intentional time delay. CE, CSA, and UL listings confirm the fuse meets recognized North American and international safety standards.

This fuse is suited for general-purpose branch circuit and equipment protection where a K5-class fast-acting cartridge is specified. Typical applications include control panels, machine tool circuits, HVAC control wiring, and other low-current equipment circuits requiring reliable overcurrent protection. It mounts in a standard cartridge fuse holder and is handled by licensed electricians or qualified maintenance technicians during panel service or equipment repair.
